    still need some ideas why my tac wont hold poi, when you first install scope it hits 12 inches left 10 high, if you adjust scope to dead center it will shoot good for awhile then go off. sent back to pse they replaced rail put new scope on and its the same, went to the dealer and they pulled a new bow and scope done the same thing, like i said in a thread before hawk says at 20 yards it should be within 3 inches of center, both bow rails are 1/16 off and i dont think i should need to shim a 1500 dollar bow. the parallex is set.
